Method Detail

getStartOffset

int getStartOffset()

Offsets are not available for anything outputted by the SqlParser.

Specified by:

getStartOffset in interface PlsqlNode

Returns:

Always returns -1.

getOperandType

byte getOperandType()

Returns:

The operand type. Found in SqlConstants under the prefix OPNT (OPeraNd Type).

getStringType

byte getStringType()

Returns:

If this is a string (OPNTSTR, OPeraNd Type STRing), then this returns the string type. Found in SqlConstants under the prefix STRT (STRing Type). Note that zero == STRTCONS and hence is a valid STRT value.

getStringText

java.lang.String getStringText()

Returns:

If this is a string, then this returns the text of the string.

getOperatorType

short getOperatorType()

Returns:

If this is an operator (OPNTOPT, OPeraNd Type OPeraTor), then this returns the operator type. Found in SqlOperators. Otherwise, this returns SqlOperators.OPT_invalid.

getOperandCount

short getOperandCount()

Returns:

If this is an operator, then this returns the number of operands to this operator. Otherwise, this returns zero.

getOperands

SqlExpression[] getOperands()

Returns:

If this is an operator, then this returns a non-null array containing the operands to this operator (can this be zero-length?). Otherwise, this returns a zero-length array.

getColumnBaseName

java.lang.String getColumnBaseName()

The format of an OPNTCOL is "user.table.base@networknode". If one lhs name is omitted, then the format is "table.base@networknode". If two lhs names are omitted, then the format is "base@networknode". In all cases, "@networknode" may be omitted.

Returns:

If this is a column (OPNTCOL, OPeraNd Type COLumn), then this returns the column's base name. Null if this is not a column.

getColumnTableName

java.lang.String getColumnTableName()

Returns:

If this is a column, then this returns the name of the table. Null if none.

getColumnUserName

java.lang.String getColumnUserName()

Returns:

If this is a column, then this returns the name of the user. Null if none.

getColumnNodeName

java.lang.String getColumnNodeName()

Returns:

If this is a column, then this returns the name of the network node. Null if none.
