Eloquent\Confetti\CompoundTransformInterface

interface CompoundTransformInterface implements TransformInterface

The interface implemented by compound stream transforms.

Methods

tuple<string,integer,mixed> transform(string $data, mixed $context, boolean $isEnd = false)

Transform the supplied data.

 from TransformInterface
array<TransformInterface> transforms()

Get the sequence of transforms that are applied to incoming data.

Details

public tuple<string,integer,mixed> transform(string $data, mixed $context, boolean $isEnd = false)

Transform the supplied data.

This method may transform only part of the supplied data. The return value includes information about how much data was actually consumed. The transform can be forced to consume all data by passing a boolean true as the $isEnd argument.

The $context argument will initially be null, but any value assigned to this variable will persist until the stream transformation is complete. It can be used as a place to store state, such as a buffer.

It is guaranteed that this method will be called with $isEnd = true once, and only once, at the end of the stream transformation.

Parameters

string $data The data to transform.
mixed $context An arbitrary context value.
boolean $isEnd True if all supplied data must be transformed.

Return Value

tuple<string,integer,mixed> A 3-tuple of the transformed data, the number of bytes consumed, and any resulting error.
