getVariables

public Map<String,Object> getVariables()

Description copied from interface: VariableScope

Returns all variables. This will include all variables of parent scopes too.

Specified by:

getVariables in interface VariableScope

getVariableInstances

public Map<String,VariableInstance> getVariableInstances()

Description copied from interface: VariableScope

Returns all variables, as instances of the VariableInstance interface, which gives more information than only the value (type, execution id, etc.)

Specified by:

getVariableInstances in interface VariableScope

getVariables

public Map<String,Object> getVariables(Collection<String> variableNames)

Description copied from interface: VariableScope

Similar to VariableScope.getVariables(), but limited to only the variables with the provided names.

Specified by:

getVariables in interface VariableScope

getVariableInstances

public Map<String,VariableInstance> getVariableInstances(Collection<String> variableNames)

Description copied from interface: VariableScope

Similar to VariableScope.getVariableInstances(), but limited to only the variables with the provided names.

Specified by:

getVariableInstances in interface VariableScope

getVariables

public Map<String,Object> getVariables(Collection<String> variableNames,
 boolean fetchAllVariables)

Description copied from interface: VariableScope

Similar to

invalid @link

{@link #getVariables(Collection))

}, but with a flag that indicates that all variables should be fetched when fetching the specific variables. If set to false, only the specific variables will be fetched. Dependening on the use case, this can be better for performance, as it avoids fetching and processing the other variables. However, if the other variables are needed further on, getting them in one go is probably better (and the variables are cached during one Command execution).

Specified by:

getVariables in interface VariableScope

getVariableInstances

public Map<String,VariableInstance> getVariableInstances(Collection<String> variableNames,
 boolean fetchAllVariables)

Description copied from interface: VariableScope

Similar to VariableScope.getVariables(Collection, boolean) but returns the variables as instances of the VariableInstance interface, which gives more information than only the value (type, execution id, etc.)

Specified by:

getVariableInstances in interface VariableScope

collectVariables

protected Map<String,Object> collectVariables(HashMap<String,Object> variables)

collectVariableInstances

protected Map<String,VariableInstance> collectVariableInstances(HashMap<String,VariableInstance> variables)

getVariable

public Object getVariable(String variableName)

Description copied from interface: VariableScope

Returns the variable value for one specific variable. Will look in parent scopes when the variable does not exist on this particular scope.

Specified by:

getVariable in interface VariableScope

getVariableInstance

public VariableInstance getVariableInstance(String variableName)

Description copied from interface: VariableScope

Similar to VariableScope.getVariable(String), but returns a VariableInstance instance, which contains more information than just the value.

Specified by:

getVariableInstance in interface VariableScope

getVariable

public Object getVariable(String variableName,
 boolean fetchAllVariables)

The same operation as getVariable(String), but with an extra parameter to indicate whether or not all variables need to be fetched. Note that the default Activiti way (because of backwards compatibility) is to fetch all the variables when doing a get/set of variables. So this means 'true' is the default value for this method, and in fact it will simply delegate to getVariable(String). This can also be the most performant, if you're doing a lot of variable gets in the same transaction (eg in service tasks). In case 'false' is used, only the specific variable will be fetched.

Specified by:

getVariable in interface VariableScope

getVariableInstance

public VariableInstance getVariableInstance(String variableName,
 boolean fetchAllVariables)

Description copied from interface: VariableScope

Similar to VariableScope.getVariable(String, boolean), but returns an instance of VariableInstance, which has some additional information beyond the value.

Description copied from interface: VariableScope

Specified by:

getVariableInstanceLocal in interface VariableScope

getVariableLocal

public Object getVariableLocal(String variableName,
 boolean fetchAllVariables)

Description copied from interface: VariableScope

Similar to VariableScope.getVariableLocal(String), but has an extra flag that indicates whether or not all variables need to be fetched when getting one variable. By default true (for backwards compatibility reasons), which means that calling VariableScope.getVariableLocal(String) will fetch all variables, of the current scope. Setting this flag to false can thus be better for performance. However, variables are cached, and if other variables are used later on, setting this true might actually be better for performance.

Specified by:

getVariableLocal in interface VariableScope

getVariableInstanceLocal

public VariableInstance getVariableInstanceLocal(String variableName,

setVariable

public void setVariable(String variableName,
 Object value)

Description copied from interface: VariableScope

Sets the variable with the provided name to the provided value.

A variable is set according to the following algorithm:

If this scope already contains a variable by the provided name as a local variable, its value is overwritten to the provided value.

If this scope does not contain a variable by the provided name as a local variable, the variable is set to this scope's parent scope, if there is one. If there is no parent scope (meaning this scope is the root scope of the hierarchy it belongs to), this scope is used. This applies recursively up the parent scope chain until, if no scope contains a local variable by the provided name, ultimately the root scope is reached and the variable value is set on that scope.

In practice for most cases, this algorithm will set variables to the scope of the execution at the process instance’s root level, if there is no execution-local variable by the provided name.

Specified by:

setVariable in interface VariableScope

Parameters:

variableName - the name of the variable to be set

value - the value of the variable to be set

setVariable

public void setVariable(String variableName,
 Object value,
 boolean fetchAllVariables)

The default setVariable(String, Object) fetches all variables (for historical and backwards compatible reasons) while setting the variables. Setting the fetchAllVariables parameter to true is the default behaviour (ie fetching all variables) Setting the fetchAllVariables parameter to false does not do that.

Specified by:

setVariable in interface VariableScope

setVariable

 Object value,
 ExecutionEntity sourceExecution,
 boolean fetchAllVariables)

Sets a variable as high as possible (highest parent).

Parameters:

sourceExecution - The execution where the variable was originally set, used for history data.

fetchAllVariables - If true, all existing variables will be fetched when setting the variable.
