Detailed Description

Class which writes ASCII or binary JSON streams.

The JSON format (http://www.json.org) is a generic way to store data. Houdini extends JSON to a byte-stream binary encoding (see UT_JID for details). The UT_JSONWriter class is used to write JSON (binary or ASCII) to a stream.

Member Function Documentation

static UT_JSONWriter* UT_JSONWriter::allocWriter ( UT_WorkBuffer buffer)
static

Allocate a JSON Writer which will fill a UT_WorkBuffer. Please delete when finished with the writer.

static UT_JSONWriter* UT_JSONWriter::allocWriter ( std::ostream &  os,
bool  binary,
UT_CompressionType  compressionType = UT_COMPRESSION_TYPE_NONE 
)
static

Allocate a JSON Writer which writes to an output stream. Please delete when finished with the writer.

static UT_JSONWriter* UT_JSONWriter::allocWriter ( const char *  filename,
bool  binary,
UT_CompressionType  compressionType = UT_COMPRESSION_TYPE_NONE 
)
static

Allocate a JSON Writer which writes to a named file. Please delete when finished with the writer.

static UT_JSONWriter* UT_JSONWriter::allocWriter ( UT_JSONValue value)
static

Allocate a JSON Writer which writes into a given UT_JSONValue. The value will only be set properly at the conclusion of writing. Please delete when finished with the writer.

bool UT_JSONWriter::beginUniformArray ( int64  length,
UT_JID  id 
)

When writing binary JSON files, uniform arrays can be encoded without repetition of the type information which results in a more compressed data format.

beingUniformArray() starts a uniform array. The id should be one of:

  • UT_JID_BOOL
  • UT_JID_INT8
  • UT_JID_INT16
  • UT_JID_INT32
  • UT_JID_INT64
  • UT_JID_UINT8
  • UT_JID_UINT16
  • UT_JID_REAL16
  • UT_JID_REAL32
  • UT_JID_REAL64
  • UT_JID_STRING
void UT_JSONWriter::endNewFile ( )

End a started embedded file.

bool UT_JSONWriter::endUniformArray ( int64 nwritten = 0)

End the uniform array.

Parameters
nwritten
If provided, the number of items written is returned.
Note
The JSONWriter class will automatically clamp or fill the uniform array with 0, but nwritten will return the actual number of calls to uniformWrite().
bool UT_JSONWriter::getBinary ( ) const
inline

Return whether writing binary or ASCII JSON.

End a generic array object By default, a new line will be output for pretty printing. The newline can give a hint to omit the new line before the end of the array marker.

void UT_JSONWriter::setOptions ( const UT_Options options)

Set formatting/control options base on the UT_Options. The following options are scanned:

  • int "json:precision" – ASCII float precision [9]. Note half-precision floats will use half this precision, while double precision will use twice the digits.
  • int "json:indentstep" – ASCII indent step for maps/arrays [8]
  • int "json:textwidth" – ASCII wrap lines after byte count [256]
  • bool "json:comments" – Allow comments in ASCII stream [false]
  • bool "json:prettyprint" – Pretty print ASCII stream [true]
  • bool "json:usetokens" – Binary string token compression [true]
  • bool "json:prettycompact" – Add a space after separators, a more compact pretty print matching Python [false]
