Method Detail

setParameter

public static void setParameter(java.lang.String id,
                java.lang.String value)

Set a global (or module) parameter, which is shared by all Z3 contexts. Remarks: When a Z3 module is initialized it will use the value of these parameters when Z3_params objects are not provided. The name of parameter can be composed of characters [a-z][A-Z], digits [0-9], '-' and '_'. The character '.' is a delimiter (more later). The parameter names are case-insensitive. The character '-' should be viewed as an "alias" for '_'. Thus, the following parameter names are considered equivalent: "pp.decimal-precision" and "PP.DECIMAL_PRECISION". This function can be used to set parameters for a specific Z3 module. This can be done by using <module-name>.<parameter-name>. For example: Z3_global_param_set('pp.decimal', 'true') will set the parameter "decimal" in the module "pp" to true.

getParameter

public static java.lang.String getParameter(java.lang.String id)

Get a global (or module) parameter. Remarks: This function cannot be invoked simultaneously from different threads without synchronization. The result string stored in param_value is stored in a shared location.

Returns:

null if the parameter id does not exist.

resetParameters

public static void resetParameters()

Restore the value of all global (and module) parameters. Remarks: This command will not affect already created objects (such as tactics and solvers)

setParameter(java.lang.String, java.lang.String)

ToggleWarningMessages

public static void ToggleWarningMessages(boolean enabled)

Enable/disable printing of warning messages to the console. Remarks: Note that this function is static and effects the behaviour of all contexts globally.

enableTrace

public static void enableTrace(java.lang.String tag)

Enable tracing messages tagged as `tag' when Z3 is compiled in debug mode. Remarks: It is a NOOP otherwise.

disableTrace

public static void disableTrace(java.lang.String tag)

Disable tracing messages tagged as `tag' when Z3 is compiled in debug mode. Remarks: It is a NOOP otherwise.
