Constructor Details

LegacyHandlerSubmissionExpression

public LegacyHandlerSubmissionExpression(String activePartId,
 Shell activeShell,
 IWorkbenchPartSite activeSite)

Constructs a new instance of LegacyHandlerSubmissionExpression

Parameters:

activePartId - The part identifier to match with the active part; null if it will match any active part.

activeShell - The shell to match with the active shell; null if it will match any active shell.

activeSite - The site to match with the active site; null if it will match any active site.

Method Details

collectExpressionInfo

public void collectExpressionInfo(ExpressionInfo info)

Collect expression info for a legacy handler submission. Namely the active part id and name, active shell name, active workbench window shell name and the active site name.

Overrides:

collectExpressionInfo in class Expression

Parameters:

info - the expression information object used to collect the information

Since:

3.2

computeHashCode

protected int computeHashCode()

Description copied from class: Expression

Method to compute the hash code for this object. The result returned from this method in cached in the fHashCode field. If the value returned from the method equals Expression.HASH_CODE_NOT_COMPUTED (e.g. -1) then the value is incremented by one.

This default implementation calls super.hashCode()

Overrides:

computeHashCode in class Expression

Returns:

a hash code for this object.

equals

public boolean equals(Object object)

Overrides:

equals in class Object

evaluate

public EvaluationResult evaluate(IEvaluationContext context)

Evaluates this expression. This tests the three conditions against the current state of the application (as defined by context). If a condition is null, then it matches any possible value (i.e., it is not tested at all).

Specified by:

evaluate in class Expression

Parameters:

context - The context providing the current workbench state; must not be null.

Returns:

EvaluationResult.TRUE if the conditions all matches; EvaluationResult.FALSE otherwise.

toString

public String toString()

Overrides:

toString in class Object
