Method Detail

create

public static LookupTableJAI create(int sourceType,
                                    int targetType,
                                    MathTransform1D[] transforms)
                             throws TransformException

Gets a lookup factory

Parameters:

sourceType - The source data type. Should be one of DataBuffer constants.

targetType - The target data type. Should be one of DataBuffer constants.

transforms - The math transforms to apply.

Returns:

The lookup table, or null if this method can't build a lookup table for the supplied parameters.

Throws:

TransformException - if a transformation failed.

hashCode

public int hashCode()

Returns a hash code value for this key. This is for internal use by LookupTableFactory and is public only as an implementation side effect.

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Compares the specified object with this key for equality. This is for internal use by LookupTableFactory and is public only as an implementation side effect.

Overrides:

equals in class Object
