### getNumKeys

    public int getNumKeys()

  The number of records in the database.

### getNumData

    public int getNumData()

  The number of records in the database.

  If the `Database.getStats` call was configured by the `StatsConfig.setFast` method, the count will be the last saved value unless it has never been calculated, in which case it will be 0.

### getPageSize

    public int getPageSize()

  The underlying database page size, in bytes.

### getExtentSize

    public int getExtentSize()

  The underlying database extent size, in pages.

### getPages

    public int getPages()

  The number of pages in the database.

  The information is only included if the `Database.getStats` call was not configured by the `StatsConfig.setFast` method.

### getReLen

    public int getReLen()

  The length of the records.

### getRePad

    public int getRePad()

  The padding byte value for the records.

### getPagesFree

    public int getPagesFree()

  The number of bytes free in database pages.

  The information is only included if the `Database.getStats` call was not configured by the `StatsConfig.setFast` method.

### getFirstRecno

    public int getFirstRecno()

  The first undeleted record in the database.

### getCurRecno

    public int getCurRecno()

  The next available record number.
