- org.codehaus.groovy.ast.expr.VariableExpression

- All Implemented Interfaces and Traits:
    Variable

      public class VariableExpression
      extends Expression
      implements Variable

  Represents a local variable name, the simplest form of expression. e.g. "foo".

    `` | `public ClassNode` | `getType()`
    `` | `public boolean` | `hasInitialExpression()`
    `` | `public boolean` | `isClosureSharedVariable()` Tells if this variable or the accessed variable is used in a closure context, like in the following example :
        def str = 'Hello'

    The "str" variable is closure shared.

- - ### Field Detail

    - #### public static final VariableExpression SUPER_EXPRESSION

    - #### public static final VariableExpression THIS_EXPRESSION

  - ### Constructor Detail

    - #### public VariableExpression(String name, ClassNode type)

    - #### public VariableExpression(String variable)

    - #### public VariableExpression(Variable variable)

  - ### Method Detail

    - #### public Variable getAccessedVariable()

    - #### @Override public Expression getInitialExpression()

    - #### @Override public int getModifiers()

    - #### @Override public String getName()

    - #### @Override public ClassNode getOriginType()

      Returns the type which was used when this variable expression was created. For example, getType() may return a boxed type while this method would return the primitive type.

      Returns:
        the type which was used to define this variable expression

    - #### @Override public String getText()

    - #### @Override public ClassNode getType()

    - #### @Override public boolean hasInitialExpression()

    - #### @Override public boolean isClosureSharedVariable()

      Tells if this variable or the accessed variable is used in a closure context, like in the following example :

          def str = 'Hello'
           def cl = { println str }

      The "str" variable is closure shared.
      Returns:
        true if this variable is used in a closure

    - #### @Override public boolean isDynamicTyped()

    - #### @Override public boolean isInStaticContext()

    - #### public boolean isSuperExpression()

    - #### public boolean isThisExpression()

    - #### public boolean isUseReferenceDirectly()

      For internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in future.

    - #### public void setAccessedVariable(Variable origin)

    - #### @Override public void setClosureSharedVariable(boolean inClosure)

      Use this method to tell if a variable is used in a closure, like in the following example:

          def str = 'Hello'
           def cl = { println str }

      The "str" variable is closure shared. The variable expression inside the closure references an accessed variable "str" which must have the closure shared flag set.
      Parameters:
        `inClosure` - tells if this variable is later referenced in a closure

    - #### public void setInStaticContext(boolean inStaticContext)

    - #### public void setModifiers(int modifiers)

    - #### @Override public void setType(ClassNode cn)

      Set the type of this variable. If you call this method from an AST transformation and that the accessed variable is (shared, this operation is unsafe and may lead to a verify error at compile time. Instead, set the type of the accessed variable

      Parameters:
        `cn` - the type to be set on this variable

    - #### public void setUseReferenceDirectly(boolean useRef)

      For internal use only. This flag is used by compiler internals and should probably be converted to a node metadata in future.

      Parameters:
        useRef

    - #### @Override public String toString()

    - #### @Override public Expression transformExpression(ExpressionTransformer transformer)

    - #### @Override public void visit(GroovyCodeVisitor visitor)
