Definition at line 21 of file GRXWriter+Immediate.h.
| + (instancetype) emptyWriter |
Returns a writer that, as part of its start method, finishes immediately without sending any values to its writeable.
Extends class GRXWriter.
| + (instancetype) writerWithContainer: | (id< NSFastEnumeration >) | container |
Returns a writer that iterates over the values of the passed container and pushes them to its writeable. The container is released when the iteration is over.
Note that the usual speed gain of NSFastEnumeration over NSEnumerator results from not having to call one method per element. Because GRXWriteable instances accept values one by one, that speed gain doesn't happen here.
Extends class GRXWriter.
| + (instancetype) writerWithEnumerator: | (NSEnumerator *) | enumerator |
Returns a writer that pulls values from the passed NSEnumerator instance and pushes them to its writeable. The NSEnumerator is released when it finishes.
Extends class GRXWriter.
| + (instancetype) writerWithError: | (NSError *) | error |
Returns a writer that, as part of its start method, sends the passed error to the writeable (then releasing the error).
Extends class GRXWriter.
| + (instancetype) writerWithValue: | (id) | value |
Returns a writer that sends the passed value to its writeable and then finishes (releasing the value).
Extends class GRXWriter.
| + (instancetype) writerWithValueSupplier: | (id(^)(void)) | block |
Returns a writer that pushes to its writeable the successive values returned by the passed block. When the block first returns nil, it is released.
Extends class GRXWriter.
