Detailed Description

The reference counted JSON value data (internal use).

Starting from version 0.4, the JSON value class use the reference counting tecnique (also know as copy-on-write) described in the wxWidgets documentation in order to speed up processing. The class is used internally by the wxJSONValue class which does all processing. To know more about COW see json_internals_cow

Member Data Documentation

m_commentPos

int wxJSONRefData::m_commentPos

The position of the comment line(s), if any.

The data member contains one of the following constants:

• wxJSONVALUE_COMMENT_BEFORE
• wxJSONVALUE_COMMENT_AFTER
• wxJSONVALUE_COMMENT_INLINE

Definition at line 394 of file jsonval.h.

m_comments

wxArrayString wxJSONRefData::m_comments

The array of comment lines; may be empty.

Definition at line 397 of file jsonval.h.

m_lineNo

int wxJSONRefData::m_lineNo

The line number when this value was read.

This data member is used by the wxJSONReader class and it is used to store the line number of the JSON text document where the value appeared. This value is compared to the line number of a comment line in order to obtain the value which a comment refersto.

Definition at line 407 of file jsonval.h.

m_memBuff

wxMemoryBuffer * wxJSONRefData::m_memBuff

The pointer to the memory buffer object.

Note that despite using reference counting, the wxMemoryBuffer is not a copy-on-write structure so the wxJSON library uses some tricks in order to avoid the side effects of copying / assigning wxMemoryBuffer objects

Definition at line 415 of file jsonval.h.

m_refCount

int wxJSONRefData::m_refCount

the references count

Definition at line 364 of file jsonval.h.

m_type

wxJSONType wxJSONRefData::m_type

The actual type of the value held by this object.

Definition at line 367 of file jsonval.h.

m_valArray

wxJSONInternalArray wxJSONRefData::m_valArray

The JSON array value.

Definition at line 382 of file jsonval.h.

m_valMap

wxJSONInternalMap wxJSONRefData::m_valMap

The JSON object value.

Definition at line 385 of file jsonval.h.

m_valString

wxString wxJSONRefData::m_valString

The JSON string value.

Definition at line 379 of file jsonval.h.

m_value

wxJSONValueHolder wxJSONRefData::m_value

The JSON value held by this object.

This data member contains the JSON data types defined by the JSON syntax with the exception of the complex objects. This data member is an union of the primitive types so that it is simplier to cast them in other compatible types.
