Method Details

isConstant

public static boolean isConstant(String id)

rb_is_const_id and is_const_id

isClassVariable

public static boolean isClassVariable(String id)

rb_is_class_id and is_class_id

isInstanceVariable

public static boolean isInstanceVariable(String id)

rb_is_instance_id and is_instance_id

isGlobal

public static boolean isGlobal(String id)

rb_is_global_id and is_global_id

isPredicate

public static boolean isPredicate(String id)

isLocal

@Deprecated
public static boolean isLocal(String id)

Deprecated.

rb_is_local_id and is_local_id

isSpecial

public static boolean isSpecial(String id)

We store IR special variables (e.g. %block) in scope and we want reflective Ruby methods to not see these since they are not real variables...they're special.

isAttrSet

public static boolean isAttrSet(String id)

isValidConstantName

public static boolean isValidConstantName(String id)

isValidInstanceVariableName

public static boolean isValidInstanceVariableName(String id)

isValidClassVariableName

public static boolean isValidClassVariableName(String id)

isInitialCharacter

public static boolean isInitialCharacter(int c)

isNameCharacter

public static boolean isNameCharacter(char c)

isNameString

public static boolean isNameString(String id,
 int start,
 int limit)

isRubyVariable

public static final boolean isRubyVariable(String name)

Check the syntax of a Ruby variable, including that it's longer than zero characters, and starts with either an @ or a capital letter.

isConstantInitial

public static boolean isConstantInitial(ByteList byteList)

determineSymbolNameType

public static SymbolNameType determineSymbolNameType(Ruby runtime,
 ByteList data)
