public String toString()
```
    Description copied from class: SoyData
    
    This was a required method in the old SoyData interface. For new data classes, please use interface SoyValue, which has the method coerceToString(). Converts this data object into a string (e.g. when used in a string context).
    
    Specified by:
    
    toString in class SoyData
    
    Returns:
    The value of this data object if coerced into a string.
  - toBoolean
```
@Deprecated
public boolean toBoolean()
```
    Deprecated.
    
    This was a required method in the old SoyData interface. For new data classes, please use interface SoyValue, which has the method coerceToBoolean(). Converts this data object into a boolean (e.g. when used in a boolean context). In other words, this method tells whether this object is truthy.
    Undefined is falsy.
    
    Specified by:
    
    toBoolean in class SoyData
    
    Returns:
    The value of this data object if coerced into a boolean. I.e. true if this object is truthy, false if this object is falsy.
  - equals
```
public boolean equals(Object other)
```
    Description copied from interface: SoyValue
    
    Compares this value against another for equality in the sense of the '==' operator of Soy.
    
    Specified by:
    
    equals in interface SoyValue
    
    Specified by:
    
    equals in class SoyAbstractValue
    
    Parameters:
    other - The other value to compare against.
    
    Returns:
    True if this value is equal to the other in the sense of Soy.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
