Constructor Detail

Parameter

public Parameter(ClassNode type,
                 String name)

Parameter

public Parameter(ClassNode type,
                 String name,
                 Expression defaultValue)
Method Detail

toString

public String toString()

getName

public String getName()
Description copied from interface: Variable
the name of the variable

Specified by:
getName in interface Variable

getType

public ClassNode getType()
Description copied from interface: Variable
the type of the variable

Specified by:
getType in interface Variable

setType

public void setType(ClassNode type)

hasInitialExpression

public boolean hasInitialExpression()
Description copied from interface: Variable
returns true if there is an initialization expression

Specified by:
hasInitialExpression in interface Variable

getInitialExpression

public Expression getInitialExpression()
Description copied from interface: Variable
expression used to initialize the variable or null of there is no initialization.

Specified by:
getInitialExpression in interface Variable
Returns:
the default value expression for this parameter or null if no default value is specified

setInitialExpression

public void setInitialExpression(Expression init)

isInStaticContext

public boolean isInStaticContext()

isInStaticContext in interface Variable

setInStaticContext

public void setInStaticContext(boolean inStaticContext)

isDynamicTyped

public boolean isDynamicTyped()
Specified by:
isDynamicTyped in interface Variable

isClosureSharedVariable

public boolean isClosureSharedVariable()
Specified by:
isClosureSharedVariable in interface Variable

setClosureSharedVariable

public void setClosureSharedVariable(boolean inClosure)
Specified by:
setClosureSharedVariable in interface Variable
