Repeatable in Memory Stream Reference

Parameter Name Is required? Expressions Default Value Description

initialBufferSize

NO

NO

256

This is the amount of memory that will be allocated in order to consume the stream and provide random access to it. If the stream contains more data than can be fit into this buffer, then it will be expanded by according to the bufferSizeIncrement attribute, with an upper limit of maxInMemorySize. Default value is 256 KB.

bufferSizeIncrement

NO

NO

256

This is by how much will be buffer size by expanded if it exceeds its initial size. Setting a value of zero or lower will mean that the buffer should not expand, meaning that a STREAM_MAXIMUM_SIZE_EXCEEDED error will be raised when the buffer gets full. Default value is 256 KB.

maxInMemorySize

NO

NO

1024

This is the maximum amount of memory that will be used. If more than that is used then a STREAM_MAXIMUM_SIZE_EXCEEDED error will be raised. A value lower or equal to zero means no limit. Defaults to 1024

bufferUnit

NO

NO

KB

The unit in which all these attributes are expressed. Possible values: BYTE, KB, MB, GB.

File Stored Input Stream

Parameter Name Is required? Expressions Default Value Description

maxInMemorySize

NO

NO

1024

Defines the maximum memory that the stream should use to keep data in memory. If more than that is consumed then it will start to buffer the content on disk. Default value is 256 KB.

bufferUnit

NO
