Constructor Detail

ConstantDefinition

public ConstantDefinition(String name)

ConstantDefinition

public ConstantDefinition(String name,
                  Object value)

Construct a ConstantDefinition with a constant value - for use when building defs from an ABC.

Parameters:

name - the name of the definition

value - the value of the constant

Method Detail

buildInnerString

public void buildInnerString(StringBuilder sb)

For debugging only. Produces a string such as public const N:int.

Overrides:

buildInnerString in class VariableDefinition

resolveValue

public Object resolveValue(ICompilerProject project)

Description copied from interface: IConstantDefinition

Try to calculate the constant value for this ConstantDefinition.

Specified by:

resolveValue in interface IConstantDefinition

Parameters:

project - the project to use to resolve the intializer

Returns:

the constant value of this definition, or null if one can't be determined.

resolveValueFrom

public Object resolveValueFrom(ICompilerProject project,
                      NodeBase fromNode)

Try to calculate the constant value for this Constant Definition when referenced from the passed in Node. If the passed in node is a Forward reference to this ConstantDefinition then we will return null, if it is not a forward reference this method will return the same as resolveValue above.

Parameters:

project - project to use to resolve the initializer

fromNode - the node that is referencing this constant

Returns:

the constant value of this definition, or null if one can't be determined, or if this is a forward reference, as determined by the fromNode.

resolveValueImpl

public Object resolveValueImpl(ICompilerProject project)
