Method Details

convert

public static @Nullable Expression convert(@NonNull Context context,
 int position,
 @NonNull Expression base,
 int maskPosition,
 @NonNull String maskString)

Create swizzle expressions. This method permits components containing ZERO or ONE, does typechecking, reports errors via ErrorHandler, and returns an expression that combines constructors and native swizzles (comprised solely of X/Y/W/Z).

make

public static @NonNull Expression make(@NonNull Context context,
 int position,
 @NonNull Expression base,
 byte[] components,
 int numComponents)

getKind

public Node.ExpressionKind getKind()

Specified by:

getKind in class Expression

See Also:

• Node.ExpressionKind

getBase

public Expression getBase()

setBase

public void setBase(Expression base)

getComponents

public byte[] getComponents()

copy

public @NonNull Expression copy(int position)

Specified by:

copy in class Expression

toString

public @NonNull String toString(int parentPrecedence)

Specified by:

toString in class Expression
