Detailed Description

Named buffer reader XML handler class.

Definition at line 57 of file ddlstreamer.hpp.

Public Methods

DDLStreamer (const XMLStreamerFactory *p_pParent, StreamerParams *p_pParameters, XMLFlowContext *p_pContext, XMLStreamConsumer *p_pOutput, ContentHandler *p_pHandler, bool p_fCopyStreamToOutput)

virtual ~DDLStreamer ()

bool commitStream (bool p_fFinal=false)

xML Stream commit function.
This function is called to commit a chunk or the whole of the input XML stream.
A partial commit means that the data provided since last commit is OK for processing.
A final commit means that the whole input stream has been provided and that the streamer should consider the input XML document as complete.

void makeNodeDDL (DBOBJDefinitionNode *p_pDefinitionNode, XMLStreamConsumer *p_pOutput) const

Produces the CREATE TABLE statement for a definition node.

char * getColumnDDL_Simple (const char *p_pszReducedType) const

Returns column type according to reduced type information. All alphanumeric fields are mapped as VARCHAR[DDLSTREAMER_VARCHARSIZE] and all fields are mapped as DOUBLE. This degraded mode is used when DBspec field is not present in definition.

Member Function Documentation

bool DDLStreamer::commitStream ( bool p_fFinal = false ) [virtual]

xML Stream commit function.
This function is called to commit a chunk or the whole of the input XML stream.
A partial commit means that the data provided since last commit is OK for processing.
A final commit means that the whole input stream has been provided and that the streamer should consider the input XML document as complete.

Reimplemented from SaxStreamer.

char * DDLStreamer::getColumnDDL_Simple ( const char * p_pszReducedType ) const

Returns column type according to reduced type information. All alphanumeric fields are mapped as VARCHAR[DDLSTREAMER_VARCHARSIZE] and all fields are mapped as DOUBLE. This degraded mode is used when DBspec field is not present in definition.

Parameters:

p_strReducedType (string) field reduced type.

void DDLStreamer::makeNodeDDL ( DBOBJDefinitionNode * p_pDefinitionNode,

XMLStreamConsumer * p_pOutput

) const

Produces the CREATE TABLE statement for a definition node.

Parameters:

p_pDefinitionNode (DBOBJDefinitionNode*) The definition node to translate.

p_pOutBuffer (XMLStreamBuffer*) The buffer to put statements into.
