SqlJetBtreeRecord

public SqlJetBtreeRecord(ISqlJetVdbeMem... values)

Method Detail

getFields

public java.util.List<ISqlJetVdbeMem> getFields()

Specified by:

getFields in interface ISqlJetBtreeRecord

Returns:

the fields

getRecord

public static ISqlJetBtreeRecord getRecord(SqlJetEncoding encoding,
                                           java.lang.Object... values)
                                    throws SqlJetException

Throws:

SqlJetException

getFieldsCount

public int getFieldsCount()

Specified by:

getFieldsCount in interface ISqlJetBtreeRecord

Returns:

the fieldsCount

getStringField

public java.lang.String getStringField(int field,
                                       SqlJetEncoding enc)
                                throws SqlJetException

Specified by:

getStringField in interface ISqlJetBtreeRecord

Returns:

Throws:

SqlJetException

getIntField

public long getIntField(int field)

Specified by:

getIntField in interface ISqlJetBtreeRecord

Returns:

getRealField

public double getRealField(int field)

Specified by:

getRealField in interface ISqlJetBtreeRecord

Returns:

getRawRecord

public ISqlJetMemoryPointer getRawRecord()

Assuming the record contains N fields, the record format looks like this:

hdr-size

type 0

type 1

...

type N-1

data0

...

data N-1

Each type field is a varint representing the serial type of the corresponding data element (see sqlite3VdbeSerialType()). The hdr-size field is also a varint which is the offset from the beginning of the record to data0.

Specified by:

getRawRecord in interface ISqlJetBtreeRecord

Returns:

release

public void release()

Specified by:

release in interface ISqlJetReleasable
