Method Detail

initData

public void initData(SimModel model,
                     java.lang.String headerComment)

addNumericDataSource

public void addNumericDataSource(java.lang.String name,
                                 NumericDataSource s,
                                 int maxIntegerDigits,
                                 int maxFractionDigits)

Adds a NumericDataSource to this DataRecorder with the specified name, and specified number of integral and fractional digits. The NumericDataSource generates the data to be recorded.

Specify a maxIntegerDigits of less than 0 to avoid rounding and truncating the integeral portion of the number. Similarly, specify a maxFractionDigits of less than 0 to avoid rounding and truncating the fractional portion of the number.

Note that the number is rounded if necessary when trucated. For example, with a maxFactionDigits of 2, the number 99.555 becomes 99.56.

Specified by:

addNumericDataSource in interface DataSourceRecorder

Parameters:

name - the name of the data (e.g. Number of Agents)

s - the source of the data

maxIntegerDigits - the maximum number of digits before the decimal point. A value of -1 will record all the digits.

maxFractionDigits - the maximum number of digits after the decimal point. A value of -1 will record all the digits.

addNumericDataSource

public void addNumericDataSource(java.lang.String name,
                                 NumericDataSource s)

Adds a NumericDataSource to this DataRecorder with the specified name. The NumericDataSource generates the data to be recorded.

Specified by:

addNumericDataSource in interface DataSourceRecorder

Parameters:

name - the name of the data (e.g. Number of Agents)

s - the source of the data

createObjectDataSource

public void createObjectDataSource(java.lang.String name,

                                   java.lang.String methodName)

Creates a DataSource using the specified object and the specified method name. Whenever DataRecorder.record is called, the method of this name is called on this object and the result is recorded.

Note the specified method must return an Object, that is, anything but void or a primitive. The method must be public.

Specified by:

createObjectDataSource in interface DataSourceRecorder

Parameters:

name - the name for this data source. This corresponds to the column name when this object is written out to the file

feedFrom - the object on which to call the method

methodName - the name of the method to call

createNumericDataSource

public void createNumericDataSource(java.lang.String name,
                                    java.lang.Object feedFrom,

                                    int maxIntegerDigits,
                                    int maxFractionDigits)

Creates a NumericDataSource using the specified object and the specified method name. Whenever DataRecorder.record is called, the method of this name is called on this object and the result is recorded.

Note the specified method must explicity return a double, that is, the return value of the method signature must be a double (e.g. public double ...). The method must be public.

Specified by:

createNumericDataSource in interface DataSourceRecorder

Parameters:

name - the name for this data source. This corresponds to the column name when this object is written out to the file

feedFrom - the object on which to call the method

methodName - the name of the method to call

maxIntegerDigits - the maximum number of digits before the decimal point. A value of -1 will record all the digits.

maxFractionDigits - the maximum number of digits after the decimal point. A value of -1 will record all the digits.

record

public abstract void record()

Description copied from interface: Recorder

Records the data for the current tick in tabular format. Each tick is a row, and each column is the name of the data source.

Specified by:

record in interface Recorder

writeToFile

public abstract void writeToFile()

Specified by:

writeToFile in interface Recorder

write

public abstract void write()

Description copied from interface: Recorder

Writes the recorded data out to a file in tabular format. This also does a flush on the data itself (i.e. the data is no longer stored by repast and exists only in the file). Identical to writeToFile().

Specified by:

write in interface Recorder

writeEnd

public abstract void writeEnd()

Description copied from interface: Recorder

Writes any ending matter to the file. Used internally during a batch run to write the ending time of the entire batch. A model would not typically call this method.

Specified by:

writeEnd in interface Recorder

simEventPerformed

public void simEventPerformed(SimEvent evt)

Specified by:

simEventPerformed in interface Recorder

Specified by:

simEventPerformed in interface SimEventListener

setDelimeter

public void setDelimeter(java.lang.String delim)

Sets the tabular data delimiter to the specified string. The default is ",".

Specified by:

setDelimeter in interface DataSourceRecorder

Parameters:

delim - the new delimiter.
