ConstantAwareTokenStream extends AbstractTokenStream

A list of single T_VALUE, T_NEWLINE and T_CONSTANT tokens. This is only created for LineIdentifierAssignment lines if there is at least one T_CONSTANT token in the assignment that needs to be evaluated when string'ified by the AST-builder.

Methods

__serialize()  : array<string|int, mixed>

When storing to cache, we only store FE relevant properties and skip irrelevant things. For instance $currentIndex should always initialize to -1 and does not need to be stored.

__toString()  : string

Create a source string from given tokens.

append()  : self

Stream creation.

getAll()  : array<string|int, TokenInterface>

Only used internally when one Stream is transferred to another, in particular when a TokenStream is turned into TokenStreamConstantAware.

getNext()  : TokenInterface|null

Get next token and raise pointer.

isEmpty()  : bool

We sometimes create a stream but don't add tokens.

peekNext()  : TokenInterface|null

Get next token but do not raise pointer.

reset()  : static

Reset current pointer. Typically, call this before iterating with getNext().

setAll()  : self

Only used internally when one Stream is transferred to another, in particular when a TokenStream is turned into TokenStreamConstantAware.

setFlatConstants()  : void

Set by the AstBuilder to resolve constant values. Never cached.
