All Implemented Interfaces:
Expression
public class BoundTagExpression extends AbstractExpression

  • Constructor Details

    • BoundTagExpression

      public BoundTagExpression()
      Empty Ctor for serialization

    • BoundTagExpression

      public BoundTagExpression(TagPath path)

  • Method Details

    • execute

      @Nonnull public QualifiedValue execute() throws ExpressionException
      Description copied from interface: Expression
      Compute and return the value of this expression
      Throws:
      ExpressionException

    • getOpName

      public String getOpName()
      Description copied from interface: Expression
      Return a human-readable name for the operation that this expression performs

    • getType

      @Deprecated public Class<?> getType()
      Deprecated.
      Typing is no longer enforced on expressions.

    • setType

      @Deprecated public void setType(Class<?> type)
      Deprecated.
      Typing is no longer enforced on expressions, but we can't remove the setter due to serialization.

    • _getTagPath

      public TagPath _getTagPath()

    • _setTagPath

      public void _setTagPath(TagPath path)

    • getTagPath

      public String getTagPath()

    • getTagListenerDelegate

      public TagListener getTagListenerDelegate()

    • setTagListenerDelegate

      public void setTagListenerDelegate(TagListener tagListenerDelegate)

    • shutdown

      public void shutdown()
      Description copied from interface: Expression
      Tells the expression to shutdown any polling operations.
      Specified by:
      shutdown in interface Expression

      shutdown in class AbstractExpression

    • startup

      public void startup()
