String	toString()

The value of this Declaration, if known.

True if we never need to access this declaration.

True if this is a fluid binding (in a FluidLetExp).

True if the value of the variable is the contents of a Location.

Is this an implicit 'this' parameter?

If we need a 'context' supplied from a ReferenceExp or 'this.

Does this variable need to be initialized or is default ok

Create a Location object, given that isIndirectBinding().

Note that the value of the variable is the contents of a Location.

Set the value assoociated with this Declaration.

If non-null, field is relative to base. If IS_FLUID, base points to IS_UNKNOWN Symbol.

Initialize in {@code }/{@code } rather than in {@code run}/{@code $run$}>.

This flag bit is set if this can be be acceessed from other modules. Ignored unless PRIVATE. Used when an exported macro references a non-exported name.

List of ApplyExp where this declaration is the function called. The applications are chained using their nextCall fields. The chain is not built if STATIC_SPECIFIED.

True if this is a field or method in a class definition.

Unique id number, to ease print-outs and debugging. If negative, a code to specify a builtin function.

Set if this declares a namespace prefix (as in XML namespaces).

A reference to a module instance.

Set if this is just a declaration, not a definition.

This prefix is used in field names for a declaration that has both EXTERNAL_ACCESS and IS_PRIVATE set.

If non-null, the single expression used to set this variable. If the variable can be set more than once, then value is null.

If getValue() is a constant, return the constant value, otherwise null.

Return the ScopeExp that contains (declares) this Declaration.

Create a declaration corresponding to a static field.

Parameters: cname name of class containing field fname name of static field

Similar to {@code getDeclarationFromStatic}, but also do {@code noteValue} with the field's value.

Get the line number of (the start of) this Expression. The "first" line is line 1; unknown is -1.

The value of this Declaration, if known. Usually the expression used to initialize the Declaration, or null if the Declaration can be assigned a different value after initialization. Note that this is the semantic value: If the INDIRECT_LOCATION is set, then getValue is the value after de-referencing the resulting Location. An exception is if isAlias(); in that case getValue() is an expression yielding a Location which needs to be de-referenced to get this Declaration's actual value.

True if we never need to access this declaration.

True if this is a fluid binding (in a FluidLetExp).

True if the value of the variable is the contents of a Location.
