SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
A variable binding represents either a field of a class or interface, or a local variable declaration (including formal parameters, local variables, and exception variables).
This interface is not intended to be implemented by clients.

public boolean isField()
true

and false
if this is the binding for a local variablepublic String getName()
getName

public ITypeBinding getDeclaringClass()
The declaring class of a field is the class or interface of which it is a member. Local variables have no declaring class. The field length of an array type has no declaring class.

public int getVariableId()
Local variables inside methods: Local variables (and parameters) declared within a single method are assigned ascending ids in normal code reading order; var1.getVariableId()<var2.getVariableId() means that var1 is declared before var2.
Local variables outside methods: Local variables declared in a type's static initializers (or initializer expressions of static fields) are assigned ascending ids in normal code reading order. Local variables declared in a type's instance initializers (or initializer expressions of non-static fields) are assigned ascending ids in normal code reading order. These ids are useful when checking definite assignment for static initializers (JLS 16.7) and instance initializers (JLS 16.8), respectively.
Fields: Fields declared as members of a type are assigned ascending ids in normal code reading order; field1.getVariableId()<field2.getVariableId() means that field1 is declared before field2.
public Object getConstantValue()

String
, the result is the string itself. If the variable has
no compile-time computed value, the result is null
