Method Detail

toJavaString

public java.lang.String toJavaString()

Description copied from class: LValue

Convert to a Java String

Overrides:

toJavaString in class LValue

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

luaGetType

public int luaGetType()

Description copied from class: LValue

Valid for all types: return the int value identifying the type of this value

Specified by:

luaGetType in class LValue

luaGetMetatable

public LTable luaGetMetatable()

Description copied from class: LValue

Valid for all types: get a metatable. Only tables and userdata can have a different metatable per instance, though, other types are restricted to one metatable per type. Since metatables on non-tables can only be set through Java and not Lua, this function should be overridden for each value type as necessary.

Overrides:

luaGetMetatable in class LValue

Returns:

null if there is no meta-table

toJavaInstance

public java.lang.Object toJavaInstance()

Description copied from class: LValue

Convert to a Java Object iff this is a LUserData value

Overrides:

toJavaInstance in class LValue

luaBinCmpUnknown

public boolean luaBinCmpUnknown(int opcode,
                                LValue lhs)

Overrides:

luaBinCmpUnknown in class LValue

isUserData

public boolean isUserData()

Description copied from class: LValue

Returns true if this is an LUserData

Overrides:

isUserData in class LValue
