RECORD_HEADER_SIZE
public static int RECORD_HEADER_SIZE
The size of the record header in bytes.
MfRecord
public MfRecord(InputStream in)
throws IOException Constructs a new MfRecord by reading the data from the input stream.
in - the source inputstream
MfRecord
public MfRecord(int parcount)
Creates a new MetaFileRecord with the specified capacitiy. The capacity is given in
16-Bit words. The resulting buffer has the size of 2*parcount + RECORD_HEADER.
parcount - the number of 16-Bit words stored as bulk in the record.
doesMark
public boolean doesMark()
True if this record marks the screen. Currently such records are ignored.
getLongParam
public int getLongParam(int p)
Return a 32-bit param from the given offset. Offset is in 16-bit words.
p - the parameter position in words.
getName
public String getName()
Return the name of this type of record.
getParam
public int getParam(int p)
Return a 16-bit param from the given offset. Offset is in 16-bit words.
p - the parameter position in words.
getStringParam
public String getStringParam(int p,
int len) Return a string param from the given offset. Offset is in 16-bit words.
p - the parameter position in words.
getType
public int getType()
Queries the 16-bit type of this record.
isMappingMode
public boolean isMappingMode()
True if this record affects mapping modes.
read
protected void read(InputStream in)
throws IOException Read a record from an input stream.
setLongParam
public void setLongParam(int p,
int value) Defines a 32-bit param at the given offset. Offset is in 16-bit words.
p - the parameter position in words.value - the parameter value.
setParam
public void setParam(int p,
int value) Defines a 16-bit param at the given offset. Offset is in 16-bit words.
p - the parameter position in words.value - the parameter value.
setStringParam
public void setStringParam(int p,
String s) Defines a string param at the given offset. Offset is in 16-bit words.
p - the parameter position in words.s - the parameter value.
setType
public void setType(int type)
Defines the 16-bit type of this record.
toString
public String toString()
Return debug info.
