getInt

public int getInt()

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Gets a integer value from this variable. The variable contains the information, whether it is long, short etc. If the variable contains a long value greater as the integer range, an IllegalArgumentException may be thrown or not, it depends on the implementation. If the variable is a float or double it may be convert to the integer format. If the variable is a boolean, it is converted to 0 or 1.

Specified by:

getInt in interface VariableAccess_ifc

Returns:

the value.

setInt

public int setInt(int value)

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Sets the value into the variable. If the variable is of byte or short type and the value is not able to present, an IllegalArgumentException may be thrown or not, it depends on the implementation.

Specified by:

setInt in interface VariableAccess_ifc

Parameters:

value - The value given as int.

Returns:

The value really set (maybe more imprecise).

getLong

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Gets a long value from this variable. The variable contains the information, whether it is long, short etc. If the variable is a float or double it may be convert to the long format. If the value is not able to present, an IllegalArgumentException may be thrown or not, it depends on the implementation. If the variable is a boolean, it is converted to 0 or 1.

Specified by:

getLong in interface VariableAccess_ifc

Returns:

the value.

setLong

public long setLong(long value)

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Sets the value into the variable. If the variable is of byte, short or int type and the value is not able to present, an IllegalArgumentException may be thrown or not, it depends on the implementation.

Specified by:

setLong in interface VariableAccess_ifc

Parameters:

value - The value given as int.

Returns:

The value really set (maybe more imprecise).

getFloat

public float getFloat()

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Gets the value from this variable. If the variable is in another format than float, a conversion to be will be done.

Specified by:

getFloat in interface VariableAccess_ifc

Returns:

the value.

setFloat

public float setFloat(float value)

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Sets the value from this variable.

Specified by:

setFloat in interface VariableAccess_ifc

Returns:

the value.

getDouble

public double getDouble()

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Gets the value from this variable. If the variable is in another format than double, a conversion to be will be done.

Specified by:

getDouble in interface VariableAccess_ifc

Returns:

the value.

setDouble

public double setDouble(double value)

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Sets the value from this variable. If the variable is from float type, and the range (exponent) is able to present in float, the value will be stored in float with truncation of digits.

Specified by:

setDouble in interface VariableAccess_ifc

Returns:

the value.

getString

public java.lang.String getString()

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Specified by:

isRefreshed in interface VariableAccess_ifc

requestValue

public void requestValue(long timeRequested)

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Requests a new value from the target device.

Specified by:

requestValue in interface VariableAccess_ifc

Parameters:

timeRequested - the current time, used to mark the request.

requestValue

public void requestValue()

Requests a new value from the target device with the System.currentTimeMillis()

Specified by:

requestValue in interface VariableAccess_ifc

requestValue

public void requestValue(long timeRequested,
                         java.lang.Runnable run)

Description copied from interface: org.vishia.byteData.VariableAccess_ifc

Requests a new value from the target device.

Specified by:

requestValue in interface VariableAccess_ifc

Parameters:

timeRequested - the current time

run - method which should be invoked if the request is resolved, optional operation.
